While “The Social Network” star Jesse Eisenberg slipped out the back stairway, Cameron and Tyler Winklevoss had no fear walking into the Harvard club to celebrate the film that exposed the uglier side of the creation of Facebook. “We conducted ourselves appropriately, so we weren’t concerned,” said Cameron, whose lawsuit against Facebook creator Mark Zuckerberg was depicted in the film. One aspect film producers didn’t get right, according to the twins, was just how rude White House economic adviser Larry Summers was when they asked for help in dealing with Zuckerberg. “Let’s just say he isn’t the most diplomatic person,” Cameron told us of their meeting with the then Harvard president. “We went in there feeling bad and coming out much worse.” On the other side of the party, Sony CEO Howard Stringer was twice bombarded by an excessively surgerized Faye Du naway in a wide-brimmed hat with dark hair. The star begged him to ask director David Fincher to watch her trailer for Sony Classics. “I’m stalking him. Please ask him to see the trailer,” Dunaway said.
